Accuracy-Focused Engineering We focus on our technology so BACtrack’s pro-grade series consistently outperforms. Precise Results The linear response of the Pro Series’ Xtend® Fuel Cell Sensor Technology provides precise results over the complete range of alcohol concentrations expected in the breath, from 0.000 to 0.400 % BAC. BACtrack pro-grades can accurately detect trace amounts of alcohol and reliably handle very high BACs. Consistency Pro-grade models produce the most consistent and reliable results. For example, they are more likely to show the same test result when someone is tested repeatedly in a very short period of time. This means pro-grade BACtracks...
